calculation process, horizontal hinge constraints are imposed on the front, rear, left, and right boundaries of the model, and the bottom boundary is fixed, the top boundary is free and bears... thickness, m. It can be seen from Figure 5(b) that in the dynamic calculation process, the bottom and top boundaries adopt static field boundaries, and the free field boundaries are applied at the rest......

J. Cent. South Univ. (2016) 23: 934-943 DOI: 10.1007/s11771-016-3141-x A general solution for vertical-drain consolidation with impeded drainage boundaries FU Cui-wei(付崔伟), LEI Guo-hui(雷国辉) Key... factors of drainage efficiency of top and bottom boundaries have a potentially important influence on consolidation. The boundary may be considered fully drained when the characteristic factor......
. The interface of (0001)α/(110)β has a platform-step structure, whereas / interface is flat with no steps. Key words: alloy design; high-strength titanium alloy; α″ phase; α/β interface; twin... alloys is the fine secondary acicular α phase precipitated in the β matrix [4]. These dispersed α phases and β matrix form a large number of α/β phase boundaries, hindering dislocation slip and increasing......
